Interpretation¶

Grāma-Mukhya Chaturtha
Belongs to the 4^th Mela in the ancient Grāma-Mukhya system (≈ Mela 15: Māyāmālavagowla in modern 72-Mela system).
Uses Shuddha Madhyama (Ma1) and Shuddha Nishāda (Ni1).
Murchhana-Panchamī
The raga is derived from the 5^th mode (Murchhana) of the parent scale, shifting emphasis to Pa (Panchama) as a pivotal note.
Aṃśas (Dominant Notes)
Sa (Shadja), Ma (Madhyama), Da (Dhaivata) are emphasized. These notes define the raga’s tonal center.
Varjita Svaras (Omitted Notes)
Ga (Gāndhāra) skipped in ascent (Ārohaṇa).
Ni (Nishāda) skipped in descent (Avarohaṇa).
Resulting scale:
- Ārohaṇa: Sa Ri Ma Pa Da Sa (C D F G A C)
- Avarohaṇa: Sa Da Pa Ma Ri Sa (C A G F D C)
Nyāsa (Final Resting Note)
Phrases resolve to Sa (C), giving stability.
Apanyāsa (Secondary Resting Note)
Ma (F) acts as a secondary resolution point.
Derived Phrases (Viśiṣṭa Tānas)
a. Nyasa Tana
- Ma Ga Re Sa (F E♭ D C)
Purpose: Cadential phrase (closing).
Rule Applied: Uses Ga (E♭) only in descent (since Ga is varjita in ascent).
b. Upanta Tana
- Sa Re Ma Pa Ma (C D F G F)
Purpose: Builds tension around Ma (F) before resolving.
Rule Applied: Highlights Ma (F) as apanyāsa.
c. Puraka Tānas (Introductory Phrases)
(1) Sa Pa Da Pa (C G A G)
Focuses on Pa (G) and Da (A).
(2) Ga Pa Da Pa (E♭ G A G)
Uses Ga (E♭) only in descent (varjita in ascent).
(3) Da Ma Ga Re Sa (A F E♭ D C)
Descends with Ga (E♭), avoiding Ni.
Tetrachordal Cadence (Norm No. 13e)
Ma Re Sa (F D C) is a key closing motif.

need to edit belows¶

These are all terms related to music theory, particularly in scales, modes, and phrasing. Here’s what they mean:

Scales & Modes

Scale: A set of musical notes arranged in ascending or descending order by pitch. Example: C major scale (C-D-E-F-G-A-B-C).

Mode: A variation of a scale with a different starting note and characteristic sound. Example: Dorian mode (a minor scale with a raised 6^th).

Tonic: The first note of a scale, acting as the "home" note that gives a sense of stability. Example: In C major, C is the tonic.

Omitted Notes: Notes that are left out of a scale or chord for a specific effect. Example: In a pentatonic scale, two notes are omitted from the full seven-note scale.

Melodic & Harmonic Structure

Final Note: The last note of a piece or phrase, often reinforcing the tonic for closure.

Cadence Phrase: A musical phrase that leads to a cadence, which is a harmonic or melodic ending. Example: A V-I progression (dominant to tonic) in classical music.

Penultimate Phrase: The second-to-last phrase in a musical section, leading into the final resolution.

Complementary Phrase: A phrase that balances or responds to a previous phrase, often creating a sense of call and response.

characteristic features(lakshanas) scale(grama) mode(murchhana) tonics(amsas) omited notes

== Kedara

Time = night emotion = grave and sublime Scale = primary first mode = first tonics = Sa and Pa omitted notes = ra in ascent and Ga in descent Final note = Pa semi-final = Sa Characteristic phrases: cadence phrase -SaMaGaMaPa penultimate phrase - PaMaGaMaRaSa (1) Pa Da Sa' (2) Sa'Da Pa.

sa is ma is wrong

Nasya = resting

How These Rules Shape the Raga¶

Melodic Flow:
Ascent is pentatonic (no Ga), while descent is hexatonic (includes Ga but omits Ni).
Ma (F) and Da (A) are emphasized as pillars.
Avoidance Rules:
Never use Ga (E♭) in ascending passages (e.g., Sa Ri Ma Pa is allowed; Sa Ri Ga Ma is forbidden).
Never end a descent on Ni (B♭).
Cadential Formulas:
All phrases must resolve to Sa (C) or Ma (F).
The Ma Re Sa cadence (F D C) is mandatory for closures.

Practical Application in Composition¶

Start/End on Sa (C):
Example: Begin with Sa Re Ma Pa → Develop with Da Pa Ma Re → Close with Ma Re Sa.
Use Apanyāsa (Ma) for Pauses:
Example: Sa Re Ma (pause) Pa Da Pa Ma (pause) Re Sa.
Varjita Enforcement:
Wrong: Sa Ri Ga Ma Pa (Ga in ascent).
Correct: Sa Ri Ma Pa Da (Ga skipped).
Phrase Chaining:
Combine Nyasa Tana (F E♭ D C) + Upanta Tana (C D F G F) + Puraka Tana 3 (A F E♭ D C).

MIDI Implementation Example¶

# Generate a valid Nāṭabhairavi phrase (Python/mido)
import mido
mid = mido.MidiFile()
track = mido.MidiTrack()
mid.tracks.append(track)

notes = [65, 63, 62, 60]  # Ma Ga Re Sa (Nyasa Tana)
for note in notes:
    track.append(mido.Message('note_on', note=note, velocity=64, time=0))
    track.append(mido.Message('note_off', note=note, velocity=64, time=480))

mid.save("nyasa_tana.mid")

Key Takeaways¶

Rules: Avoid Ga in ascent, Ni in descent; emphasize Sa/Ma/Da.
Phrases: Nyasa Tana closes, Upanta Tana builds tension, Puraka Tānas decorate.
Cadence: Always resolve to Ma Re Sa or Sa.

The phrases (Tānas) of a Raga are derived systematically from its rules (Lakshanas) through combinatorial logic, while adhering to melodic constraints. Here’s how it works for your specified Raga (Nāṭabhairavi variant), along with the theoretical number of possible phrases:

Step 1: Base Rules → Phrase Construction¶

From your given Lakshanas: 1. Varjita Svaras (Omitted Notes)
- Ascent: Skip Ga (E♭) → Allowed: Sa (C), Ri (D), Ma (F#), Pa (G), Da (A).
- Descent: Skip Ni (B♭) → Allowed: Sa, Da, Pa, Ma, Ri, Ga (E♭).

Aṃśas (Dominant Notes)
Must emphasize Sa (C), Ma (F#), Da (A).
Nyāsa/Apanyāsa
Phrases must end on Sa (C) or pause on Ma (F#).
Tetrachordal Cadence
Closing formula: Ma Re Sa (F# D C).

Step 2: Phrase Derivation Process¶

A. Valid Note Sequences¶

Ascent: Sa → Ri → Ma → Pa → Da → Sa (No Ga).
Descent: Sa → Da → Pa → Ma → Ga → Ri → Sa (No Ni).

B. Generate Permutations¶

Start/End Rules:
All phrases must begin/end on Sa, Ma, or Da (Aṃśas).
Nyāsa phrases must end on Sa.
Length Constraints:
Typical phrases are 3–6 notes (e.g., Sa Re Ma, Ma Pa Da Sa).
Avoid Repetition:
No immediate note repetition (e.g., Sa Sa Ri is invalid).

C. Example Derivations¶

Nyasa Tana: Ma Ga Re Sa
Derived from the cadence rule (Ma Re Sa) + Ga allowed in descent.
Upanta Tana: Sa Re Ma Pa Ma
Emphasizes Ma (F#) as apanyāsa, skips Ga in ascent.
Puraka Tānas:
Sa Pa Da Pa: Focuses on Pa-Da oscillation.
Ga Pa Da Pa: Uses Ga only in descent.

Step 3: Calculating Possible Phrases¶

Combinatorial Estimation¶

Ascent (5 notes): Sa, Ri, Ma, Pa, Da
3-note phrases: 5 × 4 × 3 = 60 (but only ~20 valid due to rules).
Example valid: Sa Ri Ma, Ri Ma Pa, Ma Pa Da.
Descent (6 notes): Sa, Da, Pa, Ma, Ga, Ri
4-note phrases: 6 × 5 × 4 × 3 = 360 (but ~50 valid).
Example valid: Da Pa Ma Ga, Pa Ma Ri Sa.
Cadential Phrases:
Only Ma Re Sa is allowed for closure (strict rule).

Total Valid Phrases¶

Conservative Estimate: 50–100 unique phrases (after applying rules).
Common Practice: Typically 10–20 phrases are used in compositions.

Step 4: Automating Phrase Generation (Python)¶

from itertools import permutations

# Allowed notes (C=Sa, D=Ri, F#=Ma, G=Pa, A=Da, E♭=Ga)
ascent_notes = ["C", "D", "F#", "G", "A"]
descent_notes = ["C", "A", "G", "F#", "E♭", "D"]

def generate_phrases(notes, length, must_end_on=None):
    valid_phrases = []
    for perm in permutations(notes, length):
        # Apply rules: No repetition, must_end_on constraint
        if len(set(perm)) == len(perm):  # No repeats
            if must_end_on is None or perm[-1] == must_end_on:
                valid_phrases.append(perm)
    return valid_phrases

# Generate 4-note ascending phrases ending on Ma (F#)
asc_phrases = generate_phrases(ascent_notes, length=4, must_end_on="F#")
print(f"Possible ascending phrases: {len(asc_phrases)}")
# Output: e.g., ('C', 'D', 'G', 'F#'), ('D', 'G', 'A', 'F#'), ...

Key Takeaways¶

Rules → Phrases:
Varjita rules and cadences restrict note choices.
Aṃśas (Sa/Ma/Da) dominate phrase structure.
Phrase Count:
Theoretically: 100s of permutations, but practically ~50 valid.
Musically: Only 5–10 phrases are "characteristic" (e.g., Nyasa Tana).
Automation: Use combinatorial logic + rule filters to generate valid phrases.

descent_notes = ["Sa", "Da", "Pa", "Ma", "Ga", "Ri"]  # No Ni

def generate_phrases(notes, min_len=3, max_len=6, must_start=None, must_end=None):
    valid_phrases = []
    for length in range(min_len, max_len + 1):
        for perm in permutations(notes, length):
            # Check for no repetition and start/end rules
            if len(set(perm)) == length:
                if (must_start is None or perm[0] == must_start) and \
                   (must_end is None or perm[-1] == must_end):
                    valid_phrases.append(perm)
    return valid_phrases

# Generate ascending phrases ending on Sa/Ma/Da
asc_phrases = generate_phrases(ascent_notes, must_end="Sa") + \
              generate_phrases(ascent_notes, must_end="Ma") + \
              generate_phrases(ascent_notes, must_end="Da")

# Generate descending phrases ending on Sa
desc_phrases = generate_phrases(descent_notes, must_end="Sa")

print(f"Ascending phrases: {len(asc_phrases)}")

Why Characteristic Phrases (Viśiṣṭa Tānas) Differ from Other Valid Phrases¶

Characteristic phrases in a raga are not just random valid note sequences—they are culturally, theoretically, and emotionally significant motifs that define the raga’s unique identity. Here’s why they stand out:

1. Rules vs. Characteristic Phrases: Key Differences¶

Aspect	General Valid Phrases	Characteristic Phrases (Viśiṣṭa Tānas)
Derivation	Generated from scale rules (Aroha/Avaroha).	Curated by tradition, often from historic compositions.
Purpose	Demonstrate technical correctness.	Capture the raga’s bhāva (emotional essence).
Flexibility	Many permutations possible (~50–100).	Only 5–10 fixed phrases per raga.
Cadential Role	Can resolve to Sa or Ma.	Must follow strict Nyāsa (e.g., `Ma Re Sa`).
Varjita Handling	Avoid forbidden notes (Ga/Ni).	May strategically use varjita notes (e.g., Ga in descent).

2. Why Characteristic Phrases Are Special¶

(A) Historical and Guru-Śiṣya Tradition¶

Passed down through generations (e.g., Tyagaraja’s compositions in Nāṭabhairavi).
Example: The phrase "Ma Ga Re Sa" might originate from a famous kriti like "Chalamela".

(B) Emotional Signature (Bhāva)¶

Characteristic phrases highlight the raga’s mood:
Nāṭabhairavi’s Sa Re Ma Pa Ma evokes devotional pathos.
A generic Sa Ri Ma Pa lacks the same emotional weight.

(C) Raga Lakshana Reinforcements¶

They emphasize the raga’s unique rules:
Nyasa Tana (Ma Ga Re Sa):
- Uses Ga only in descent (varjita in ascent).
- Ends on Sa (Nyāsa rule).
Upanta Tana (Sa Re Ma Pa Ma):
- Highlights Ma (Apanyāsa).

(D) Tetrachordal Cadences¶

Characteristic phrases often use mandatory closing patterns:
Nāṭabhairavi’s Ma Re Sa (from Tetrachordal Cadence Norm No. 13e).
Generic phrases might end arbitrarily (e.g., Pa Da Sa).

3. Example: Nāṭabhairavi’s Characteristic vs. Generic Phrases¶

Phrase Type	Example	Why It’s Special
Characteristic	`Ma Ga Re Sa`	Uses Ga only in descent; closes with Nyāsa.
Characteristic	`Sa Re Ma Pa Ma`	Apanyāsa on Ma; emphasizes raga’s pillars.
Generic Valid	`Sa Ri Ma Pa`	Correct but lacks emotional signature.
Generic Valid	`Da Pa Ma Ga`	Follows rules but not iconic.

4. How to Identify Characteristic Phrases¶

Look for Recurring Motifs in compositions (e.g., "Chalamela" for Nāṭabhairavi).
Check Sangatis (Embellishments): Characteristic phrases are often elaborated.
Consult Raga Lakshana Texts: e.g., "Ragalakshana" by Govindaacharya.

5. Practical Implications¶

Composition: Use characteristic phrases for authenticity.
Improvisation: Generic phrases are for filler material; characteristic phrases for highlights.
Learning: Musicians memorize these phrases first (e.g., "Sarali Varisa" exercises).

Key Takeaway¶

Characteristic phrases are the "DNA" of a raga—they embody its soul, while generic valid phrases are just "grammatically correct" sequences.

Would you like a MIDI comparison of generic vs. characteristic phrases to hear the difference?

Can We Mix Two Ragas in a Song?¶

Yes! But it must be done carefully to maintain aesthetic and traditional integrity. Here’s how to blend ragras effectively:

1. Legal Ways to Mix Ragas¶

(A) Raga-Mālā (Garland of Ragas)¶

Definition: A composition that sequentially uses multiple ragras in different sections.
Example:
Pallavi in Mohanam → Anupallavi in Kalyani → Charanam in Hamsadhwani.
Tyagaraja’s "Raga Sudha Rasa" uses 5 ragras in one kriti.

Definition: Shifting the sruti (tonic) to derive a new raga.
Example:
Mohanam (C D E G A) → Shift tonic to D → Hindolam (D E G A C).

(C) Raga Sankirna (Hybrid Raga)¶

Definition: A new raga created by blending aspects of two parent ragras.
Example:
Kapi = Kharaharapriya + Hindolam.
Behag = Durga + Desh.

(D) Brief Phrase Borrowing (Alankāra Prayōga)¶

Definition: Using short motifs from another raga without fully switching scales.
Example:
In Shankarabharanam, briefly borrowing "Ni Sa" from Kalyani.

2. When Mixing is Allowed¶

✅ In Folk/Cinema Music (e.g., Ilaiyaraaja’s "How to Name It" mixes Kalyani & Mohanam).
✅ In Thillanas/Tarangams (e.g., Brinda-Mukta’s ragamalika thillanas).
✅ In Fusion/Experimental Music (e.g., Shankar Mahadevan’s "Breathless" blends Hindustani & Carnatic).

3. When Mixing is Forbidden¶

❌ In Traditional Carnatic Krithis (e.g., Tyagaraja’s compositions must stay pure).
❌ If It Breaks Raga Lakshana (e.g., adding Ga in Shuddha Saveri ascent ruins its identity).
❌ In RTP (Ragam-Tanam-Pallavi) unless explicitly a Ragamalika.

4. Practical Tips for Blending Ragas¶

Shared Notes: Choose ragras with overlapping swaras (e.g., Mohanam & Hindolam share C D E G A).
Smooth Transitions: Use common phrases (e.g., "Sa Ri Ga" in Shankarabharanam & Kalyani).
Tala Alignment: Keep the tala cycle consistent during transitions.
Emotional Harmony: Pair ragras with similar moods (e.g., Kalyani (romantic) + Begada (joyful)).

5. Famous Examples¶

"Raghuvamsa Sudha" (Kriti) – Kadanakuthuhalam + Hindolam.
"Madhuvanti + Yaman" (Hindustani Fusion) – Ustad Rashid Khan.
"Kurai Onrum Illai" (Film Music) – Bhairavi + Sindhu Bhairavi.

6. How to Experiment Safely¶

Start with Raga Pairs that share scales:
Mohanam + Hindolam (Graha Bhedam siblings).
Shankarabharanam + Kalyani (both use Shuddha Nishadam).
Use a Drone to anchor the Sa-Pa during transitions.
Record & Analyze: Check if the blend feels natural or forced.

Key Takeaway¶

Mixing ragras is an art, not a rule—done well, it creates magic; done poorly, it sounds chaotic. Study ragamalikas and fusion masters before experimenting!

Python Script to Generate Multiple MIDI Files (One per Phrase)¶

Here are individual MIDI files for each Nāṭabhairavi phrase, generated using Python's mido library. Each phrase is saved as a separate MIDI file for easy playback or integration into music software.

import mido
from mido import Message, MidiFile, MidiTrack

# Map swaras to MIDI notes (C4=60, Sa = C)
swara_to_midi = {
    "Sa": 60, "Ri": 62, "Ga": 63, "Ma": 65,  # Ma is F# (tivra)
    "Pa": 67, "Da": 69, "Ni": 70
}

# Define phrases (using swaras)
phrases = {
    "Nyasa_Tana": ["Ma", "Ga", "Ri", "Sa"],          # Ma Ga Re Sa
    "Upanta_Tana": ["Sa", "Ri", "Ma", "Pa", "Ma"],  # Sa Re Ma Pa Ma
    "Puraka_Tana_1": ["Sa", "Pa", "Da", "Pa"],      # Sa Pa Da Pa
    "Puraka_Tana_2": ["Ga", "Pa", "Da", "Pa"],      # Ga Pa Da Pa
    "Puraka_Tana_3": ["Da", "Ma", "Ga", "Ri", "Sa"] # Da Ma Ga Re Sa
}

# Generate one MIDI file per phrase
for phrase_name, swaras in phrases.items():
    mid = MidiFile()
    track = MidiTrack()
    mid.tracks.append(track)

    # Add notes (quarter notes, 480 ticks per beat)
    for swara in swaras:
        note = swara_to_midi[swara]
        track.append(Message("note_on", note=note, velocity=64, time=0))
        track.append(Message("note_off", note=note, velocity=64, time=480))

    # Save to MIDI file
    mid.save(f"{phrase_name}.mid")

print("Generated MIDI files: Nyasa_Tana.mid, Upanta_Tana.mid, etc.")

Output: 5 MIDI Files¶

Nyasa_Tana.mid
Notes: F# (Ma), E♭ (Ga), D (Ri), C (Sa)
MIDI: [65, 63, 62, 60]
Upanta_Tana.mid
Notes: C (Sa), D (Ri), F# (Ma), G (Pa), F# (Ma)
MIDI: [60, 62, 65, 67, 65]
Puraka_Tana_1.mid
Notes: C (Sa), G (Pa), A (Da), G (Pa)
MIDI: [60, 67, 69, 67]
Puraka_Tana_2.mid
Notes: E♭ (Ga), G (Pa), A (Da), G (Pa)
MIDI: [63, 67, 69, 67]
Puraka_Tana_3.mid
Notes: A (Da), F# (Ma), E♭ (Ga), D (Ri), C (Sa)
MIDI: [69, 65, 63, 62, 60]

How to Use:¶

Run the script (requires mido: pip install mido).
Load the generated .mid files into DAWs (Ableton, FL Studio) or notation software (MuseScore).
Adjust tempo/duration by modifying time=480 (480 ticks = quarter note).

Need Adjustments?¶

Change Sa (Base Note): Replace C4=60 with another MIDI note (e.g., Sa=72 for C5).
Add Rhythm: Use time=240 for eighth notes or add drums.

Todi	8	Devotional, Sorrowful	Uses flat Ga (Gāndhāram), Da (Dhaivatam) for haunting beauty.	"Kaddanu Vaariki" (Tyagaraja)
Shubhapantuvarali	45	Anguish, Longing	Chromatic phrases (e.g., Sa Ga₂ Ma₁ Pa Da₁).	"Marivere" (Shyama Sastri)
Ahiri	20	Melancholic, Divine Feminine	Ga & Ni komal evoke deep pathos.	"Rama Nee Samanamevaru"
Nata Bhairavi	20	Ancient, Meditative	Ga & Ni varjita in ascent; shadowy descent.	"Chalamela" (Annamacharya)
Varali	39	Fierce, Cosmic	Dissonant intervals (Sa-Ga₂-Da₁).	"Kanaka Shaila" (Papanasam Sivan)

B. Intellectual & Complex¶

Kharaharapriya (22) – All 12 notes allowed; vast emotional range ("Chakkani Raja").
Simhendramadhyamam (57) – Exotic due to Ma₂ (tivra) + Da₁ (komal) ("Marakoti").
Ritigowla – Hindustani-esque; blends Ga₂ & Ma₂ for introspection ("Nanu Palimpa").

2. Hindustani Ragas (North Indian)¶

Raga	Thaat	Mood (Bhāva)	Why It’s Deep?	Example Performance
Darbari Kanada	Asavari	Royal, Heart-Wrenching	Slow, heavy Gamakas on Ga (komal).	Amir Khan’s Raga Darbari
Miyan Ki Malhar	Kafi	Monsoon, Devotion	Ni komal + Ma tivra = divine longing.	"Garjat Barsat" (Bhimsen Joshi)
Marwa	Marwa	Sunset, Mystical	No Pa; unresolved tension.	"Piya Ke Milana Ki Aas" (Abdul Karim Khan)
Shree	Purvi	Sacred, Twilight	Ga & Ni komal + Ma tivra.	"Shree Rag" (Ravi Shankar)
Malkauns	Bhairavi	Hypnotic, Meditative	Pentatonic + flat Ga/Dha/Ni.	"Albela Sajan" (Bade Ghulam Ali)

3. Ragas for Specific Deep Emotions¶

Emotion	Carnatic Raga	Hindustani Raga
Divine Sorrow	Todi, Ahiri	Darbari Kanada, Marwa
Mystical Quest	Shubhapantuvarali	Shree, Malkauns
Cosmic Awe	Varali, Ritigowla	Miyan Ki Malhar
Existential Depth	Kharaharapriya	Bhairav, Lalit

4. What Makes These Ragas "Deep"?¶

Microtonal Nuances:
Todi’s Ga₂ (flat Ga) or Darbari’s elongated komal Gandhar.
Asymmetrical Scales:
Marwa omits Pa, creating unresolved tension.
Historical Weight:
Ahiri linked to Meera Bhajans, Varali to ancient temple rituals.
Philosophical Lyrics:
Compositions often explore mortality, devotion, or cosmic unity.

5. How to Compose with Deep Ragas¶

Start with a Drone (Sa-Pa or Sa-Ma) to ground the raga’s gravity.
Use Slow, Ornamented Phrases:
In Todi: Emphasize Sa → Ga₂ → Ma₁ → Pa with meends (glides).
Avoid Western Chords:
These ragas thrive in monophonic melody (no harmony).
Study Masters:
Carnatic: Semmangudi (Todi), M.S. Subbulakshmi (Ahiri).
Hindustani: Amir Khan (Darbari), Kishori Amonkar (Marwa).

Key Takeaway¶

These ragas are not for casual listening—they demand patience and emotional investment. To master them:
- Learn their characteristic phrases (e.g., Todi’s "Sa Ga₂ Ma₁ Da₁ Sa").
- Sing/play them slowly to absorb their microtones.
- Pair with meaningful lyrics (e.g., Tyagaraja’s kritis on surrender).

Do Phrases from One Raga Match Another Raga?¶

Short Answer:
- Some phrases overlap (especially in ragras with similar scales).
- But characteristic phrases (Viśiṣṭa Tānas) are usually unique to a raga.

Here’s a detailed breakdown:

1. When Phrases Overlap¶

A. Shared Scales (Same Notes)¶

Example 1:
Mohanam (Sa Ri Ga Pa Da) and Bhoopali (Sa Ri Ga Pa Da) share identical scales, so many phrases overlap.
Shared phrase: Sa Ri Ga Pa works in both.
Example 2:
Shankarabharanam (Sa Ri Ga Ma Pa Da Ni) and Bilawal (Sa Ri Ga Ma Pa Da Ni) share the major scale.
Shared phrase: Sa Re Ga Ma Pa fits both.

Mohanam (C D E G A) shifted to D becomes Hindolam (D E G A C).
Phrase E G A C exists in both but feels different due to tonic shift.

C. Common "Bridge" Notes¶

Kalyani (Sa Ri Ga Ma Pa Da Ni) and Shankarabharanam (Sa Ri Ga Ma Pa Da Ni) share all notes but differ in Ma (tivra vs. shuddha).
Sa Ri Ga Ma in Kalyani uses F#, while in Shankarabharanam it’s F natural.

2. When Phrases Are Unique¶

A. Characteristic Phrases (Viśiṣṭa Tānas)¶

These define a raga’s identity and rarely match others:
- Mohanam: Pa Da Sa Ri Ga (ascending pentatonic).
- Hamsadhwani: Sa Ri Ga Pa Sa (no Ma/Ni).
- Todi: Sa Ga₂ Ma₁ Da₁ Sa (komal Ga/Dha).

B. Varjita (Forbidden Notes)¶

Nāṭabhairavi: Skips Ga in ascent → Sa Ri Ma Pa Da ≠ Shankarabharanam (allows Ga).
Bhairavi: Uses all 12 notes, but phrases like Ni Sa Ga Ma are unique due to microtones.

C. Gamakas (Ornamentations)¶

Even if notes match, gamakas make phrases distinct:
- Kalyani’s Ga Ma Pa has heavy oscillations on Ma (F#).
- Shankarabharanam’s Ga Ma Pa is straighter (no F#).

3. How to Check if a Phrase Fits Another Raga¶

Compare Scales:
If both ragras share all notes, generic phrases may overlap.
Example: Sa Ri Ga fits Mohanam, Bhoopali, and Shuddha Saveri.
Check Varjita Rules:
If a phrase uses forbidden notes, it won’t fit.
Example: Sa Ga Ma is invalid in Nāṭabhairavi (Ga skipped in ascent).
Analyze Nyāsa/Apanyāsa:
If the phrase ends on a non-Nyāsa note, it feels "foreign".
Example: Pa Da Sa fits Mohanam (ends on Sa) but not Hindolam (Nyāsa = D).
Listen to Gamakas:
Kharaharapriya’s Ga Ma Pa vs. Kalyani’s Ga Ma Pa sound different due to ornamentation.

4. Practical Examples¶

Phrase	Fits Ragas	Doesn’t Fit Ragas	Reason
`Sa Ri Ga Pa`	Mohanam, Bhoopali	Nāṭabhairavi	Nāṭabhairavi skips Ga.
`Sa Ga Ma Pa`	Shankarabharanam	Kalyani	Kalyani uses Ma₂ (F#).
`Ma Ga Re Sa`	Nāṭabhairavi	Hamsadhwani	Hamsadhwani has no Ma.
`Pa Ma Ga Re`	Todi	Mohanam	Todi uses komal Ga (E♭).

5. Key Takeaways¶

✅ Generic phrases (e.g., Sa Ri Ga) often match between similar-scale ragras.
❌ Characteristic phrases (e.g., Todi’s Sa Ga₂ Ma₁) are unique.
🎵 Gamakas and Nyāsa make even shared phrases feel different.

To compose a song using phrases from a specific raga (e.g., Nāṭabhairavi) when you have MIDI files of all its phrases, follow this step-by-step workflow:

1. Understand the Raga's Structure¶

Arohana (Ascent) & Avarohana (Descent):
For Nāṭabhairavi:
Ascend: Sa Ri Ma Pa Da Sa (C D F# G A C)
Descend: Sa Da Pa Ma Ri Sa (C A G F# D C)
Avoid: Ga (E♭) in ascent, Ni (B♭) in descent.
Key Phrases (Tanas):
Use the MIDI phrases you generated earlier (Nyasa Tana, Upanta Tana, etc.) as building blocks.

2. Load MIDI Phrases into a DAW¶

Import the MIDI files into a Digital Audio Workstation (DAW) like:
Ableton Live
FL Studio
Logic Pro
MuseScore (for notation-based composition)

Example (Ableton Live Workflow):¶

Drag MIDI files into the arrangement view.
Stretch/align phrases to match your tempo.
Layer with a drone (Sa-Pa) for authenticity (e.g., C + G notes sustained).

3. Compose Using Raga Rules¶

a) Melody (Using Phrases)¶

Start/End on Nyāsa (Sa/C):
Begin with Nyasa_Tana.mid (Ma Ga Re Sa).
End on Sa (C).

Chain Phrases Smoothly:
Example progression:

Nyasa Tana → Upanta Tana → Puraka Tana 1 → Puraka Tana 3 → Nyasa Tana (closing)

MuseScore Notation:

b) Rhythm (Lay with Tala)¶

Use a Carnatic tala (e.g., Adi Tala: 8-beat cycle) or a simple 4/4 beat.
Align MIDI phrases to the tala’s samam (1^st beat) for emphasis.

c) Harmony (Optional)¶

Drone: Sustain Sa (C) and Pa (G) in the background.
Light Harmony: Use chords sparingly (e.g., C major, F# diminished).

4. Advanced: Generate New Phrases (Python)¶

If you want to create variations programmatically:

# Generate a new Nāṭabhairavi phrase (Sa Ri Ma Pa Da Sa)
from music21 import *
scale = scale.MelodicMinorScale("C")  # Approximate Nāṭabhairavi
phrase = [60, 62, 65, 67, 69, 60]   # Sa Ri Ma Pa Da Sa
s = stream.Stream()
for note in phrase:
    s.append(note.Note(note, quarterLength=1.0))
s.write("midi", fp="new_phrase.mid")

5. Validate with Raga Rules¶

Check:
No Ga (E♭) in ascent, no Ni (B♭) in descent.
Emphasize Sa, Ma, Da (C, F#, A).
Tools:
Use Sonic Visualizer to plot pitch contours.
Carnatic music theory apps like "Raga Surabhi" for reference.

Render to WAV/MP3 in your DAW.
Notation: Export as sheet music (MuseScore) for live performers.

Key Takeaways¶

Build blocks: Use pre-made MIDI phrases as motifs.
Resolve to Sa: Always return to the root note.
Avoid varjita swaras: Skip forbidden notes (Ga/Ni here).
Layer with drone/tala: For authenticity.
